Hi, and welcome to the forum!You need to enable Object Physics flag on the camera and create some static physics objects on your scene which you don't want the camera to pass through. Please, take in mind that this method won't give descent results if the camera is being moved to fast.

But next step - insering .json in html is sad. I know network and local work of browser and can laod your exaple96 with cube.But I have texture, camera animation and physiks of objects.Application examples 24.2 and 24.3 too simple for me?

Must I I use "24.4 Developing Apps Within the SDK" for generating html?

Now I am konfused. I read: "Option "-p" points at the name of the directory where the project is."What is the project? . Perhapse /deploy/assetsTMy project? Or project.py?more:"Option "-a" (not necessary) points at the html file relative to which the app willbe constructed."Is it Html lik 24.3 "Creating Apps Quickly"?more: "With the "-b" parameter (optional) the engine’s directoryable options: link (default) - the engine file is linked from" What is engine?

Hello.You do not need to use compilation of your application to watch a scene.Take a look at this tutorial, please. But this example does not use a physical simulation. For using the physical simulation, you should add "physics_enabled: true," in the "init" - function.
